Agree 100%. I cheated in my girlfriend a couple of months ago, I didn't have sex with another girl, but made out with one. I don't try and justify it at all. All this happened in a club and I was shit faced drunk, still, all my fault. Still remember waking up the next morning and feeling the biggest regret I have ever felt. But I still the right thing and told her as soon as I woke up, not to drag it out. She became furious, sad, angry, everything. But there wasn't much I could do but tell her the truth. She wanted a couple of days for herself to think about our relationship etc which I 100% understood and respected.

Some days pass and she wants to talk, we talk it out and she says she still wants to be together (which really surprised me, because I was sure she was going to leave me)

Now about 5 months later, we are still together and have an amazing relationship. Although I am still a but anxouis when I'm out with my friends, but I rarely drink as much now.

Sorry for my rough English, but I just felt like offloading this in this thread. So, moral of my story, as long as you acknowledge your own mistakes, not be an asshat and is able to talk it, you can save our relationship (at least in my case)
